1911 WW1 Springfield barrel
 

I have a colt mfg. barrel for the 1911 that is obviously not wartime production. It has the interlased HP and a step up 1inch 9/10 from the breach face. I can click my fingernail on it. It does not have the K on it. It is much better production than a wartime barrel. Do you guys think this could bet transisional? And what is a very good ww1 barrel worth as to a very good transitional? Thanks, I will try to figure out my scanner , camera and stuff. Again. No luck.

the barrel with the interlaced HP on top of the chamber was used by Colt in new production Militaries 1918 to 1919, ser# range from about 425,000 to 710,000. I have had a Model of the U.S. Army in the 600,000 ser# range with such a barrel, and I understand it to be correct for that period of WWI production.

I have never seen a "K" mark on a barrrel. Perhaps you are referring to the "H" found on the top of the breech face on much of Colt Barrel production? If so, barrels from about SER#25,000 to 720,000 shouldn't have those if they are marked with the several variations of "HP" on the top of the chamber (including intertwined).

Hope this helps.

The interlaced HP and the step in front of the chamber are consistent with a transitional barrel, but the lack of a K in front of the lugs would be atypical. The other thing to check for is whether the bottom of the hood is chamfered.

Transitional barrels are much rarer than similar WW1 barrels.

Thanks Trigger and Gene, It has been in a box of parts I retrieved from storage. A little note I had attached said 1924 Transitional. If the hood is the protrusion centered with and to the left of the HP it is not chamfered.
